Description

Technical Field

[0001] This utility model relates to the technical field of massagers, and in particular to a flexible massage device. Background Technology

[0002] Existing back massage devices require a housing as the moving carrier and track for the mechanism. Therefore, they all have a plastic housing as the cavity for the movement of the mechanism. Since the housing usually has a guide track and a travel sensor in the middle, the area outside the massage mechanism will create a foreign object sensation on the part of the body that comes into contact with the body when the body is being massaged or not. This is especially true in scenarios such as shared cinemas, which affects the comfort of the experience.

[0003] Existing massage devices all have fixed shells, either straight or curved. Therefore, when used in scenarios such as chairs and sofas, they cannot change shape to fit the back of the placed surface, resulting in the massage device not conforming to the curves of the human body and affecting the comfort of the experience.

[0004] However, massage devices cannot be completely limp; flexible materials cannot simply replace rigid ones. Because the walking mechanism needs to move back and forth to massage different areas, if all materials are flexible, the walking mechanism and the rack and pinion mechanism will not mesh well, leading to unstable movement. How to achieve a massage device that flexibly conforms to the curves of the human body while ensuring a stable drive connection between the rack and pinion mechanism is a pressing technical problem that needs to be solved.

[0005] In view of this, this utility model addresses the many shortcomings and inconveniences caused by the imperfections in the design of existing back-moving massage devices, and has been developed through in-depth research, improvement and trial production. Utility Model Content

[0006] The purpose of this invention is to provide a flexible massage device to improve the problem that existing walking massage devices cannot flexibly conform to the curves of the human body while ensuring stable drive between the rack and the walking mechanism.

[0007] To achieve the above objectives, the solution of this utility model is:

[0008] A flexible massage device includes: a massage mechanism, a flexible rack assembly, a traveling gear assembly, and a guide limiting mechanism; the traveling gear assembly is connected to the transmission mechanism of the massage mechanism and meshes with the flexible rack assembly; the guide limiting mechanism is fixedly connected to the massage mechanism; a rack groove for mounting the flexible rack assembly is provided between the guide limiting mechanism and the massage mechanism; the traveling gear assembly is correspondingly arranged with the rack groove; a guide fitting seat is provided on the rack groove that abuts against the flexible rack assembly and corresponds to the traveling gear assembly; the retaining teeth of the flexible rack assembly are arranged upwards; and the traveling gear of the traveling gear assembly meshes with the flexible rack assembly downwards.

[0009] Furthermore, the guide fitting seat includes a plane disposed at the top center and an arc surface that slopes outward and downward from both ends of the plane, the plane corresponding to the position of the traveling gear set.

[0010] Furthermore, the flexible rack assembly includes a flexible rack and a flexible conductive strip. The guide limiting mechanism has a probe PCB board and a probe disposed on the probe PCB board in the rack groove. The probe is elastic, and one end of the probe abuts against the flexible conductive strip.

[0011] Furthermore, the massage mechanism includes a mechanism housing, a drive mechanism, a transmission mechanism, and a massage head assembly. The drive mechanism and the transmission mechanism are disposed inside the mechanism housing. The transmission mechanism is connected to the drive mechanism, and the massage head assembly is connected to the transmission mechanism. The massage heads of the massage head assembly protrude to the top of the mechanism housing for massaging the massage area. The traveling gear assembly is connected to one end of the mechanism housing that is connected to the flexible rack assembly.

[0012] Furthermore, the driving mechanism includes a drive motor and a drive screw. The drive screw is connected to the output end of the drive motor, and the drive motor is fixedly installed inside the core housing. The transmission mechanism includes a drive gear, a transmission gear, a transmission shaft, an eccentric wheel, an eccentric wheel limiting bracket, and an eccentric wheel cover. The drive gear is a double gear, with one gear meshing with the drive screw and the other gear meshing with the transmission gear. The transmission gear is fixed together with the transmission shaft. The eccentric wheel is fixedly installed on the transmission shaft. The eccentric wheel limiting bracket is sleeved on the eccentric wheel. The massage head assembly is sleeved on the eccentric wheel limiting bracket. The eccentric wheel cover is sleeved on the transmission shaft and fixed together with the eccentric wheel. The eccentric wheel limiting bracket and the massage head assembly are located between the eccentric wheel and the eccentric wheel cover.

[0013] Furthermore, the bottom end of the eccentric wheel limiting bracket is provided with a limiting post, and the core housing is provided with a limiting groove for the limiting post to move; the connection position between the massage head assembly and the eccentric wheel limiting bracket is provided with a movable groove, and the eccentric wheel limiting bracket is provided with a movable block that can move within the movable groove.

[0014] Furthermore, the traveling gear set is configured with a flexible rack corresponding to the flexible rack set. The traveling gear set is disposed inside the core housing of the massage mechanism, and one end of the traveling gear set corresponding to the flexible rack set protrudes out of the core housing and meshes with the flexible rack. The traveling gear set includes a rotating shaft gear and a traveling gear. The rotating shaft gear is fixedly connected to the transmission shaft. The traveling gear is a double gear, in which one gear meshes with the rotating shaft gear and the other gear meshes with the flexible rack.

[0017] Furthermore, the flexible rack assembly has two flexible racks, which are spaced apart. The two ends of the two flexible racks are connected together by rack support frames, and the flexible conductive strip is connected to one of the flexible racks.

[0018] With the above structure, when a user performs a walking massage using this flexible massage device, the transmission mechanism of the massage core drives the walking gear set to move synchronously. During the massage, the flexible rack set is deformed under pressure, allowing the massage core to fully contact the massage area and improve massage comfort. The rack groove between the massage core and the guide limiting mechanism guides and limits the flexible rack set and the walking gear set. As the walking gear set moves along the flexible rack set, regardless of how the flexible rack set deforms, the meshing position between the flexible rack set and the walking gear set is always rigidly supported by the guide fitting seat, ensuring that the walking gear set always maintains meshing transmission with the flexible rack set and guaranteeing stable movement of the walking gear set and the massage core.

[0046] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0047] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0048] like Figures 1 to 17 As shown, this utility model discloses a flexible massage device, which includes a massage mechanism 10, a flexible rack assembly 20, a traveling gear assembly 30, and a guide limiting mechanism 40. The traveling gear assembly 30 is connected to the transmission mechanism of the massage mechanism 10 and meshes with the flexible rack assembly 20. The guide limiting mechanism 40 is fixedly connected to the massage mechanism 10. A rack groove 401 for mounting the flexible rack assembly 20 is provided between the guide limiting mechanism 40 and the massage mechanism 10. The traveling gear assembly 30 is correspondingly arranged with the rack groove 401. A guide fitting seat 402 is provided on the rack groove 401 that abuts against the flexible rack assembly 20 and corresponds to the traveling gear assembly 30.

[0049] When a user performs a walking massage using the flexible massage device of this utility model, the transmission mechanism of the massage core 10 drives the walking gear set 30 to move synchronously. During the massage process, the flexible rack set 20 is deformed under pressure, allowing the massage core to fully contact the massage area and improve massage comfort. The rack groove 401 between the massage core 10 and the guide limiting mechanism 40 guides and limits the flexible rack set 20 and the walking gear set 30. As the walking gear set 30 moves along the flexible rack set 20, regardless of how the flexible rack set 20 deforms, the position where the flexible rack set 20 meshes with the walking gear set 30 is always rigidly supported by the guide fitting seat 402, ensuring that the walking gear set 30 always maintains meshing transmission with the flexible rack set 20, and guaranteeing that the walking gear set 30 and the massage core can move stably.

[0050] like Figure 6 and Figure 7 As shown, the guide fitting seat 402 includes a plane 403 disposed at its top center and an arc surface 404 inclined outward and downward from both ends of the plane 403. The plane 403 corresponds to the position of the walking gear set 30, providing rigid support for the walking gear set 30 and ensuring stable driving of the walking gear set 30. The arc surface 404 on both sides of the plane 403 can ensure that the flexible rack set 20 will not be broken.

[0051] like Figure 8 As shown, the massage mechanism 10 includes a mechanism housing 1, a drive mechanism 2, a transmission mechanism 3, and a massage head assembly 4. The drive mechanism 2 and the transmission mechanism 3 are disposed inside the mechanism housing 1. The transmission mechanism 3 is connected to the drive mechanism 2, and the massage head assembly 4 is connected to the transmission mechanism 3. The massage heads 41 of the massage head assembly 4 protrude to the top of the mechanism housing 1 for massaging the massage area. The walking gear set 30 is connected to the bottom of the mechanism housing 1.

[0052] In this embodiment, the movement housing 1 includes an upper housing 11 and a lower housing 12 that is correspondingly fastened to the upper housing 11. The drive mechanism 2 includes a drive motor 21 and a drive screw 22. The drive screw 22 is connected to the output end of the drive motor 21. The drive motor 21 is fixedly installed inside the movement housing 1. The transmission mechanism 3 includes a drive gear 31, a transmission gear 32, a transmission shaft 33, an eccentric wheel 34, an eccentric wheel limiting bracket 35, and an eccentric wheel cover 36. The drive gear 31 is a double gear, one of which is a helical gear and the other is a spur gear. The helical gear meshes with the drive screw 22, and the other spur gear meshes with the transmission gear 32. The transmission gear 32 is fixed together with the transmission shaft 33. The eccentric wheel 34 is fixedly mounted on the transmission shaft 33. The eccentric wheel limiting bracket 35 is sleeved on the eccentric wheel 34. The massage head assembly 4 is sleeved on the eccentric wheel limiting bracket 35. The eccentric wheel cover 36 is sleeved on the transmission shaft 33. The eccentric wheel cover 36 is fixed together with the eccentric wheel 34. The eccentric wheel limiting bracket 35 and the massage head assembly 4 are located between the eccentric wheel 34 and the eccentric wheel cover 36.

[0053] The working principle of the massage mechanism 10 is as follows: the drive motor 21 drives the drive screw 22 to rotate, the drive screw 22 drives the drive gear 31 meshing with it to rotate, the drive gear 31 drives the transmission gear 32 and the transmission shaft 33 to rotate, and when the transmission shaft 33 rotates, the eccentric wheel 34 rotates accordingly, and drives the massage head assembly 4 set between the eccentric wheel 34 and the eccentric wheel cover 36 to perform a swinging action to achieve massage.

[0054] See Figure 8 and Figures 11 to 16 The number of massage head groups 4 and the structure of massage heads 41 can be set according to the actual needs of the product. The massage head group 4 includes at least one group. Each massage head group 4 includes a massage head 41 and a massage seat 42. The bottom end of the massage seat 42 is sleeved on the eccentric wheel limiting bracket 35, and the top end of the massage seat 42 is sleeved on the massage head 41. To limit the movement trajectory of the massage head assembly 4, a limiting post 351 is provided at the bottom of the eccentric wheel limiting bracket 35 to control the rotation amplitude of the eccentric wheel limiting bracket. A limiting groove 13 is provided on the lower housing 12 of the mechanism housing 1 for the limiting post 351 to move. The cooperation between the limiting post 351 and the limiting groove 13 can control the range of left and right sway of the massage head assembly 4. The inner ring of the massage seat 42 is provided with a movable groove 421 to control the range of forward and backward sway of the massage seat 42. A movable block 352 that can move within the movable groove 421 is provided at the fitting position of the eccentric wheel limiting bracket 35 and the massage seat 42. The cooperation between the movable block 352 and the movable groove 421 can control the range of forward and backward sway of the massage head assembly 4. In this embodiment, the massage head assembly 4 has two sets. The drive mechanism 2 is located in the middle of the mechanism housing 1, and the two sets of massage head assemblies 4 are located on both sides of the drive mechanism 2.

[0055] The flexible rack assembly 20 includes a flexible rack 201 and a flexible conductive strip 202. There is at least one flexible rack 201. When there is only one flexible rack 201, it is located at the bottom center of the massage mechanism 10. A corresponding set of traveling gears 30 is provided. In this embodiment, there are two flexible racks 201, spaced apart. The two ends of the two flexible racks 201 are connected together by a rack support frame 203. The flexible conductive strip 202 connects to one of the flexible racks 201. The rack groove 401 of the guide limiting mechanism 40 is provided with a probe PCB board 50 and a probe 501 disposed on the probe PCB board. The probe 501 is elastic, and its top end abuts against the bottom end of the flexible conductive strip 202. The elastic probe 501 allows the probe to recover promptly after the flexible conductive strip 202 deforms, ensuring the conductivity between the probe 501 and the flexible conductive strip 202. In this embodiment, the teeth of each flexible rack 201 of the flexible rack group 20 are arranged facing upwards, and the flexible conductive strip 202 is arranged at the bottom of one of the flexible racks 201.

[0056] The walking gear set 30 is configured to correspond to the flexible rack 201 of the flexible rack set 20. The walking gear set 30 is disposed inside the core housing 1 of the massage mechanism 10, and its bottom protrudes out of the core housing 1 and meshes with the flexible rack 201. In this embodiment, the walking gear set 30 has two sets, and the two sets of walking gear sets 30 correspond to two flexible racks. The walking gear set 30 includes a rotating shaft gear 301 and a walking gear 302. The rotating shaft gear 301 is fixedly connected to the transmission shaft 33. The walking gear 302 is a double spur gear, in which one spur gear meshes with the rotating shaft gear 301 and the other spur gear meshes with the flexible rack 201. When the drive motor 21 of the massage mechanism 10 is driven, it drives the transmission shaft 33 to rotate. The transmission shaft 33 drives the rotating shaft gear 301 that is meshed with it to rotate, thereby driving the walking gear 302 to move back and forth along the flexible rack 201 to realize walking massage.

[0057] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
